SOAP-MOLD.

SPECIFICATION formingrpart of ."*Letters Patent No. $795,028, dated March 11, 1902. Application led July 31, 1901. Seria] No. 70,365. (No model.)

To all whom t may concern:

Be it known that I, WASHINGTON BERRY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Soap-Molds, of which the following is a specilication.

This invention relates to improvements in molds for prod uc'ingY cakes of soap vcontaining inserts.

The primary object of my device is to provide a mold in which a mass of soap may be cast around properly spaced and located inserts in sucha manner that the mold may be separated from the mass of molded soap and the mass of soap may be out up into numerous cakes each containing an insert.

My present invention relates especially to a mold which is adapted for convenient and commercial use in the production of laundry and transparent soap and the like. Y These'and such other objects as may hereinafter appear are attained by the devices illustrated in the accompanying drawings, in which-- Figure 1 represents across-section through a soap-mold containing my improvements. Fig. 2 represents a side elevation of the same with part of the side broken away. Figs. 3, 4, and 5 show details of construct-ion. Fig.

6 indicates anend eleva-tion, partly brokenaway, of a modified form of my invention. Fig. 7 shows a side elevation, partly broken away, of the mold shown in Fig. 6. Fig. 8 is a horizontal section on the line 8 8 of Fig; 7.

Figs. 9 and l0 are enlarged details of the construction of the modified form shown in Figs. 6, 7, and 8; and Fig. Il illustrates a modification in the manner of locating the inserts.

Like letters of reference indicate corresponding parts in the several figures of the drawings. Y Y.

In the art of soap-.making it iscustomary-to cast laundry soap in large masses in a knockdovwn mold. carried on trucks. After the soap has solidified the sides of the mold are removed, leaving the solid mass of soap upon the trucks, and this mass is then cut into cakes in any convenient manner, but usually bypushing the truck against a tightlystretched wire, which cuts cleanly thrcu gh the mass of soap at anyr desired point.

.In the drawings'l have shown my invention embodied in a mold of this general description. Referring by letter to the accompanying drawings, A indicates trucks,` upon which is f mounted a base-board B, upon the upper sur face of which is attached a base-plate C,which is provided with a number of properly-spaced screw-threaded perforations c.

D indicates side boards, to the inner faces of which and adjacent to their lower edges are attached supports d. The simplest form of these supports consists of angle-irons, as shown in the drawings.. v

E indicates end boards provided with like supports e.

F indicates clamping-bars disposed at each end of the mold and, if desired, also midway between the ends and con nected by stay-bolts G, which extend through clamping-bars F, side boards D, and across the mold are formed with a head at one endv and are engaged by nuts g at the other end.

H indicates end irons, the ends of which are tted within slots in the side boards D.

In assembling my mold the side boards D are putin place, resting uponthe supports d; f

the end irons H are fitted within slots provided for. them in the side boards D; and, the side 'boards' being held rmly in position, the end boards E are then put in place resting upon their supports c, and inner faces thereh of adjacent to their lower edges abutting against oorrespondin g ends of the base-board B,th'einner faces of the end boardsE adjacent totheir'upper ends abutting against the end irons H. The clamping-bars F and stay-bolts G are then put in position, the stay-bolts passing behind and pressing tightly against the end boards E. The bolts g are then` IOO the depending flange of which is cut away I at its ends, so that While the ends of the horizontal fiange lit within the notches t' the ends of the depending liange abut against the inner face of the vertical flange of the side irons I.

In assembling my mold the nutsg upon the stay-bolts G should not be fully tightened until the cross-irons J have all been placed in position, the nuts being then tightened. The cross-irons are securely clamped between the side irons I on each side of the mold and are held rigidly in position thereby. The horizontal flanges of the cross-irons J are provided with open slotsj. K represents supporting-rods, upon which are mounted the inserts L. These inserts are properly centered and spaced apart upon the rods K in'any convenient manner, preferablyin the manner described in my concurrent application of even date herewith. As shown, the inserts L are provided with perforations. These perforations are of such a size as to furnish a snug fit for the rods K. In practice it is found that While such a lit will allow the inserts to be placed upon the rods K and to be moved to any desired point the friction between the rods and the under surfaces of said perforations will serve perfectly tohold the inserts suspended upon the rods at any desired point. The inserts having been mounted upon the rods K, the rods are placed1 in the mold between the cross-irons J. The upper ends of the rods are then placed in the slots j and the lower screw-threaded ends of the rods K are screwed into the perforations c in the base-plate G. This serves not only to properly locate the rods within the mold, but as the lower ends of the rods are screwed into the base-plate C the knobs lo onthe upper ends of the rods are brought tightlyinto engagement with the upper surface of the crossirons J, and so the rods K are securely and accurately held in proper position. When all of the rods carrying theirl inserts have been placed in position, the mold is ready for the plastic or liquid soap, which is poured into the top of the mold between the crossirons J until the mold is lled. When the soap has cooled and solidified, the rods K are unscrewed from the base-plate C and are drawn directly upward out of the mold and out of the inserts mounted thereon, leaving the mass of soap with a plurality of inserts located therein at regular distances in all directions. The mold may now be taken apart, leaving the mass of soap, with its inserts, upon the trucks, and the soap may then be cut into bars in any usual or convenient manner, each cake containing one of the inserts L, or it may be cut into bars, each bar containing a number of inserts regularly spaced apart Within the bar.

In case it is desired to make cakes of soap containing oblong inserts, which, if centrally mounted on the rods K, as previously described, would have a tendency to sag, each insert maybe mounted upon two of the rods or Wires K, as illustrated in Fig. 1l, which shows a cake of soap containing an oblong insert L (indicated in dotted lines) and mount ed upon two rods or wires K.

In Figs. 6, 7, and 8 I have shown a modification of my device, the object of such modil'ication being to do away with the objections and difficulties which might arise from the length of therods which might be required in the use of my device in the form shown in Figs.. l and 2. In all general respects the mold shown in Figs. 6, 7, and 8 is the same as that previously described; butin this modilied form I pass the krods K horizontally through the mold, the width of which is usually less than its height, thereby enabling me to use shorter rods. In this modified form I provide supports d for the side boards D, which supports are attached to the base-board B and project outwardly along the side edges thereof. Instead of mounting a base-plate upon the base-board I substitute a side plate e', mounted upon -one of the side boards D. I provide the inner faces of the end boards E with end plates M, which are provided with accurately-spaced notches m, which receive the ends of the notched bars N, which extend horizontally along one side of the mold from end to end. The rods K are inserted in this form of the mold with one end screwed into the side plate e' and the other end resting in the slots n in the bars N.` While with this form of my invention it is possible to use plain unthreaded rods or even wires or cords and to dispense also with the knobs la, I prefer to have the rods K screw-threaded at the ends which engage' the side plates c and to have the opposite ends thereof provided with the knobs k. These knobs are drawn tightly against the outer faces of the bars N when the rods are screwed into the side plate c. To protect these knobs from being entirely embedded in the soap and also to prevent leakage from the mold, I provide the side board O with recesses o, which receive the knobs 7a when the mold is assembled. The inner face of the side board O, adjacent to these recesses, is brought in close contact with the outer faces of the bars N when the stay-bolts are tightened.

When the modified form of my device has been filled with soap, the recesses 0 will be kept substantially free from soap, and when the soap has solidified and the mold is taken apart the knobs k will be found projecting from one side of the soap mass sufliciently to enable their ready vmanipulation for the purpose of unscrewing the rods K and withdrawing the same from the inserts and from the soap.

While I have shown the preferred forms of my improved mold, I of course do not wish to be confined to the exact features of construction therein shown, as these features may be modilied in many respects Without departing from the spirit of my invention.
